This looks like a variation of the willow tree pattern, but probably not for export. Quality looks more like BW wares made in Canton but the pigment itself appears like Dehua blue/white ware. Judging by the base it is probably about mid-Qing dynasty.

You can try looking at the Mount Vernon estate museum, which was George Washington's estate.

You can see the 1830s-1870s canton plates looking similar.  China was going through a bit of upheaval during that time, especially around that porcelain making areas, with the Opium wars, Taiping Rebellion, etc, and the quality degraded tremendously for these types of plates.
